Large mobile fans

FANERGY XL

Maximum thrust. Fastest ventilation.

Large mobile fans for fire fighting are used for the ventilation and venting of tunnel systems or large volume buildings and in the event of fire can purge smoke and heat by means of positive pressure as quickly as possible.

A large fan of Rosenbauer is designed as an axial fan with curved blades and guide vanes and made for maximum thrust. Depending on the operational tactics, flows can be built up, increased and even reversed.

Rosenbauer has performed simulations of fire scenarios in cooperation with the Institute for Internal Combustion Engines and Thermodynamics at the Graz University of Technology and determined the following parameters for the construction of the fans:

In the event of a fire in a tunnel, flue gases and heat build-up present a large risk. On the one hand they endanger people stuck in the tunnel, on the other hand emergency crews are prevented from advancing to the scene of the accident.

The spread of the gases is significantly influenced by flows, caused by the chimney effect, as well as effects of the weather and weather conditions.

The use of a mobile FANERGY XL fan largely allows emergency crews a risk-free advancement to the scene of the accident with "the wind at their backs".
